22 actions →How this library is built
- Sourced from research: meta-analyses, trials, and large cohort studies, not generic wellness content.
- Evidence-graded: every action that makes a specific health claim is labeled Strong evidence or Emerging evidence (promising, earlier); settled basics and how-to methods deliberately carry no grade.
- Safety-screened: each action passes a two-lens (physical + mental) harm review; anything that can't clear both is dropped or softened.
- No inflation: nothing is hyped beyond what its evidence supports. Educational, not medical advice.
